Title: Electric instrumentation alarm generating system
Inventor: IWAKI HIROYUKI
IPC: G21C17/00
Filed: 1988-08-22
Abstract: PURPOSE:To maintain a color environment in which a human being can easily cope with an abnormal situation by informing the human being of the abnormal signal of a plant, etc., by a sounding means and adjusting color illumination when the abnormal signal is received by a central supervising electronic computer. CONSTITUTION:When an abnormal signal 1 from a plant 100 is inputted to a central supervising electronic computer 5, the computer 5 sounds a voice alarm generating device 7 through an electronic computer 6 for a voice alarm and lights an indicator lamp 2. Further, the computer 5 displays abnormality contents on a CRT 8 and prints the contents by an announcement typewriter 9. Continuously, a color adjusting electronic computer 10 on-line-connected with the central supervising electronic computer 5 discriminates the significance of the abnormal situation and sounds either a bell 4 or a buzzer 3. Next, when the human being informs the color adjusting electronic computer 10 of the recognition of abnormality by pressing an abnormality confirming switch 11, a color adjusting device 13 changes the color of an illumination 12 into blue.

Title: Circuit-probing device
Inventor: KATABUCHI TAKESHI
IPC: G01R31/00
Filed: 1993-08-20
Abstract: PURPOSE:To provide a circuit-probing device wherein a circuit which contains an inductance is not discriminated indirectly on the basis of a difference in a resistance value or of the existence of the inductance but the circuit can be displayed directly. CONSTITUTION:A distribution line in which it is to be probed whether an apparatus having an inductance is connected or not is provided with power supply means 7, 3 by which an intermittent current at a frequency higher than a commercial power-supply frequency is made to flow, with 3 comparison means R which compares a voltage drop portion by the intermittent current with a reference voltage and with a display means 9 which, when an output is given from the comparison means 8, judges and displays the distribution line to which the apparatus having the inductance is connected. Consequently, the title probing device can be used in the same sense as a tester and a buzzer in conventional cases. Since the value of an inductance in a circuit is not displayed but it is displayed whether an inductance is interposed or not, the circuit can be discriminated easily and instantaneously without relying on the judgment of a human being.

Title: Magnetic recording and reproducing device
Inventor: OCHI ATSUO
IPC: G11B5/02
Filed: 1982-11-24
Abstract: PURPOSE:To increase the number of rotary magnetic heads without increasing the number of channels of a rotary transformer by transmitting/receiving signals between a rotary cylinder circuit and a fixed cylinder circuit through the rotary transformer and setting up power frequency within the transmission band of the rotary transformer and at the low frequency part of a recording/reproducing signal. CONSTITUTION:A reproducing signal from a rotary magnetic head 1a is amplified through an alteration switch 6 and transmitted to the fixed cylinder side through a head selecting circuit 14 and a rotary transformer 19. At the recording, a recording signal is amplified through a rotary transformer 18 and transmitted to heads 1a, 1b through the alteration switches 6, 7. In case of the recording system of a low frequency- converted color signal, the band of a recording/reproducing signal occupies several hundred KHz to several MHz. Therefore a signal included in said band is applied to the rotary transformers 18, 19. It is preferable to set up the channels of rotary transformers 20, 21 to a band other than said band. When a signal amplifier circuit is set up on a rotary cylinder, the transmission frequency of electric power to be supplied to a power supply circuit on the rotary cylinder should be set up close to the lower limit frequency of the low frequency-converted color signal and within the transmission band of the rotary transformers.

Title: Production of glass
Inventor: AOKI MIKIO
IPC: C01B33/158
Filed: 1985-09-19
Abstract: PURPOSE:In producing glass by sol-gel method, to reduce drying volume and to obtain glass in high yield and in a short drying time, by drying gel in a drying container having a double or triple cover whose holes are shifted. CONSTITUTION:In production of glass by sol-gel method, gel is put in a drying container having a double or triple cover whose holes are shifted and dried. When the gel is dried by using the container, air has to travel longer distance than in a case with a single cover when the air passes through the cover. Therefore, when steam evaporated from the gel goes to the outside, velocity of molecules is relaxed at a certain degree since a passageway is bent. Dried air coming in similarly from the outside is blended with humid air so the open air has almost no influence on the gel. Air flow does not occur at all by existence of distance from gel to the cover and by intervals between the first cover and the second cover and exerts no bad influence on the gel.
